Specification of Letters Patent.

Application filed August 2, 1907. serial No. 386,830.

To atl whom it may concern.'

Y Be it known that I, JOHN C. Rnisrnn, ryesiding at Eagle Lake, in the county of Colorado and State of Texas, have invented certain new and useful Improvements in Seals, of which the following is a specification.

My invention relates to certain new and useful in'iprovements in seals and it particularly relates to that type of seals known in the art as car door seals and the like and it particultlrly has for its object to provide a seal of this character of a very simple and eiiective construction which will readily and effectively serve its intended purposes and which will prevent tampering with the seal without destroying or mutilating the same.

My invention comprises certain novel construction, combination and arrangement of parts, all of which will be rst described in detail, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which z- Figure 1, is a perspective view of my invention, showing the position of the parts just prior to being locked. Fig. 2, is a` similar view before t-he strip is bent. Fig. 3, is a. vertical longitudinal section showing the position of the parts as they are in Fig. 1. Fig. t, is a similar view showing the position of the parts when locked. Fig. 5, is a cross section on the line 5-5 of Fig. 4. Fig. 6, is a detail view of the housing before being attached. Fig. 7, is a detail view of the locking plates. Fig. 7a, is a detail, plan view of the locking plates assembled. Fig. 8, `is a detail View of the stud. Fig. 9, is a detail view of a slightly modified form of my invention hereinafter specifically referred to. Figs. 10 and 11, are detail views hereinafter referred to. Fig. 12, is a form similar to Fig. 2, of another modified form of my invention. Fig. 13is a central vertical longitudinal section of the form of my invention shown in Fig. 12. Fig. 14, is a detail, inverted, plan view of one end thereof. Fig'. 15, is a perspective view of the hous ing, used in the form of my invention shown in Fig. 12. Fig. 16, is a perspective view of a modified form of locking plate. Fig. 17, is a diagrammatic plan view thereof.

Referring now to the accompanying drawings in which like characters of reference indicate like parts in all of the figures, 1 represents the flat sheet metal strip, which at one end is provided with a slightly elongated slot or aperture L t and at the other end with an aperture 6.

At a suitable distance from the end having the aperture 6, is a third aperture 3, and midway between the apertures 3 and 6 the strip is weakened by notches 2 or apertures or otherwise as may be found convenient, to form a bending line ruiming across the strip.

Between the bending line of the stra and the end having' the aperture 6 is a smal slot 5 to receive the tongue 13 of the housing 'T that is held over the aperture 6 by the bent. over edges 14; and the tongue 13, as indicated. Nithin the housing and held in place by the shoulders 11 thereof is a pair of sheet metal locking members 9, each of which is provided with triangularly arranged perforations 9EL which open into a central perforation 15 so as to form catch portions 10, as shown. The central apertures 15 of the plates tl are directly in alinement with the aperture 6 and the plates 9 are so arranged that when superimposed as shown in Fig. 7a, the triangularly arranged apertures 91 will be closed, leaving only the central aperture 15 open. IThis prevents tampering with the seal and also prevents the insertion of a wire or other tool into the housing to unlock the seal.

l Held within the aperture 3 to project in the direction opposite tothe crown of the housing 7 see Fig. 2) is a stud S, having a web 8a, a shank Sb and a head SC to cooperate with the locking springs or catch portions lOrof the locking plates 9.

In applying my invention for use, the strip 1 is first strung through the part to be secured and bent as shown in Fig. 1, until the aperture et receives the stud 8 after which the locking end having the housing is bent on its weakened line over the stud until the stud enters the housing through the aperture 6, passing therethrough and through the apertures 15 in the spring locking plates until the catch portions 10-10 engage the head 8C of the stud and lock it securely in place.

By bending the locking end at the weakening line it forms a crown for the end of the strip having the aperture t when the In Fig. 9 I have shown a slightly modified form of my invention in Which the stud is placed in the aperture 6 instead of in the aperture 3, and the housin is secured in place over the aperture 3, this being a mere reversal of the parts, see Fig. l.

In Figs. l() and 1.1, I have shown slightly modified forms of the strip l to indicate different Ways in which the weakening line can be formed, for instance, by a corrugation, as shown in Fig. 10, or by cross perforations as shown in Fig. ll.

In Figs. 12 to 17 inclusive, I have shown a slightly modified form of my invention, by reference to which it will be seen that the housing 7 is of curved shape at the ends as at 7a and in lieu of the tongue 13 the strip lis notched as at I, and the housing 7 has its edge 7 1'" swaged over the strip l, as shown in Figs. l2 and 13. In this form of my invention also the stud S is secured to the strip l by riveting or upsetting its end 8X, as shown, and the stud may be formed With a head 8C of any desired shape. In this form vof my invention also the locking member 9 is formed of a single piece and bent on the line 9x to fold over as shown in Fig. i6, and form the locking member'.

From the foregoing it Will be seen that I have provided a very simple and effective construction of seal in which means are provided for securing the stud to the strip, which means consists in upsetting a portion of the stud, as indicated in Fig. l2, after the stud has been passed through the strip l and thus lock it to the strip. It will be seen that means are also provided for holding the spring locking member immovable Within the housing. v

From the foregoing description taken in connection with the accompanying drawings it is thought the complete construction, operation and many advantages of my invention Will be readily apparent to those skilled in the art to which it appe'rtains, and I desire to say that slight changes in the detailed construction, combination and arrangement of parts can be made Without departing from the scope of the appended claims or the spirit of the invention.

VVha-t I claim is l. In a seal, the combination with a metallic strap having apertures near its ends, of a stud secured near one end, a housing secured over the apertured end of the strap adjacent the stud, and a plurality of superimposed locking means Within the housing, said strap having a weakened bendingportion between the housing and the stud, substantially as shown and described.

2. In a seal, the combination With a strap having apertures near its ends, of a stud secured near one end, a housing secured over the apertured end of the strap adjacent the stud, and locking means Within the housing, said locking means comprising a pair of superimposed plates, each having a central aperture and a series of triangularly arranged apertures, substantially as shown and described.

3. In a seal, the combination With a strap having apertures near its ends, of a stud secured near one end, a housing secured over the lapertured end of the strap adjacent the stud, and looking means `Within the housing, said locking means comprising a. pair of superimposed plates, each having a central aperture and a series of triangularly arranged apertures, the apertures of one plate being arranged to be covered by the other plate, substantially as shown and described.

4. In a seal, the combination with a strap, of a housing held over one end thereof, said strap having an aperture communicating with said housing, a stud secured to another portion of the strap and adapted when the strap is folded to project through said aperture, and locking means Within the housing cooperating With said stud, said locking means comprising a pair of superimposed plates each having tongues for engaging the stud, the free end of said strap being provided With an aperture to be engaged by said stud.

5. In a seal, the combination With a strap, of a housing held over one end thereof, said strap having an aperture communicating with said housing, a stud secured to another portion of the strap and adapted When the strap is folded to project through said aperture, locking means Within the housing coperating with said stud, said locking means comprising superimposed plates each having a central aperture, and a series of triangularly arranged apertures to form tongues to coperate With the stud, the free end of said strap being provided With an aperture to be engaged by said stud.
